CROSS REFERENCE TO RELATED APPLICATION

This application claims priority of U.S. Provisional Patent Application No. 62/032,745, filed on Aug. 4, 2014, entitled CONCEALED IMPACT GLOVE, the entire contents of which are hereby incorporated herein by reference.

BACKGROUND

The present invention relates to gloves and, more particularly, to a covered glove for protecting a wearer against impact.

In numerous industrial trades, workers run a risk of serious hand injuries. For example, in the oil and gas industry, workers in drilling and exploration are frequent victims of hand injuries. These workers often handle large pipes and heavy tools, such as wrenches. These items are typically used in mud, crude oil and lubricants. The difficulty in securely holding pipes and tools in the presence of mud, crude oil and lubricants often leads to impacts to the dorsal, or back, side of the hand. These impacts often lead to broken bones to the hand and fingers as well as the finger joints.

Gloves typically worn in the oil and gas industry are either cut and sewn, or knit gloves with an impact protective layer adhered to the exterior dorsal surface of the glove. This construction has several shortcomings. The gloves can be bulky, expensive and may not provide durable impact resistance and waterproofing. Often the impact protection material is not smooth or continuous and therefore snags on tools, machines and clothing, traps debris, and may break or chip when exposed to abrasive contact. Some gloves marketed as waterproof may feature waterproof membranes inside the glove. However, gloves with membranes inside the glove usually still absorb water and other liquids into the glove up to the membrane. While technically waterproof in that a user's your hand does not get wet from the elements, the glove can act like a sponge soaking up water and weighing down the hand.

Thus, there exists a need for improved impact resistant gloves and waterproof gloves that remedy the shortcomings of the prior art.

DETAILED DESCRIPTION

A glove 10 according to an embodiment of the present invention is shown in FIGS. 1 to 6. As shown in FIGS. 1 to 3, the glove 10 has an inner glove 12 with fingers 16, 18, 20, 22, thumb 24, a front palm portion 26, a back portion 28 and a cuff 30. A dorsal (back) side of the inner glove 12 has a protective member 32 secured to the fingers 16, 18, 20, 22, thumb 24 and the back portion 28 (covering metacarpal bones of a hand). The protective member 32 may be a single continuous piece shaped to fit the fingers, thumb and back portion or may be separate pieces for one or more of the fingers, thumb and back portion. Additionally, the protective member 32 may be segmented to increase flexibility and mobility. There may be spaces between protective member segments, such as over joints.

The protective member 32 is preferably configured to protect both the metacarpal bones and the phalanges of a wearer as well as the metacarpophalangeal and interphalangeal joints. In an embodiment, the protective member 32 is formed of thermoplastic rubber (TPR). In another embodiment, the protective member 32 is formed of liquid silicone rubber (LSR). The protective member may be made from other materials, such as nitrile butadiene rubber (NBR), polyvinyl chloride (PVC), polyurethane (PU), polymers, rubber, silicone, plastic, gel, foams such as ethylene vinyl acetate (EVA) foams, polyvinyl alcohol (PVA) foams, and memory foams, metal, glass fibers, glass beads, carbon, high strength fibers and aramid fibers and combinations thereof, depending on factors such as, for example, the intended use of the gloves, the flexibility desired by a wearer and the weight desired by a wearer. Additionally, depending on the intended application and user preferences, the protective member may be configured to cover at least a subset of the fingers, thumb, back portion and palm portion.

Additionally, depending on the intended application and user preferences, the protective member 32 may have multiple layers with different properties. In an embodiment, the protective member 14 comprises an inner layer having a first hardness and an outer layer having a second hardness, the second hardness being greater than the first hardness.

In an embodiment, the protective member 32 is raised above a dorsal surface of the back portion 28 of the glove for increased protection. The protective member 32 may have a height of between about 0.1 mm and about 20 mm. In a preferred embodiment, the protective member 32 has a height of between about 0.3 mm and about 0.8 mm. The protective member 32 is secured to the inner glove 12 through stitching, heat application, sonic welding, use of an adhesive or other methods known to those of skill in the art.

As shown in FIGS. 4 to 6, once the protective member 32 is secured to the inner glove 12, an outer glove 34 is placed over both the protective member and the inner glove and secured to at least one of the protective member and the inner glove. Like the inner glove 12, the outer glove 34 is configured with fingers 36, 38, 40, 42, thumb 44, a front palm portion 46, a back portion 48 and a cuff 50. In a preferred embodiment, the outer glove 34 is sized to fit snugly over the inner glove 12 and the protective member 32 to avoid bunching of either the inner or outer gloves. In an embodiment, the outer glove 34 is placed over the inner glove 12 and the protective member 32, and the outer glove cuff 50 is sewn to the inner glove cuff 30 to join the outer glove to the inner glove.

In an additional embodiment, an adhesive is placed on the inner glove 12 and the protective member 32 prior to the outer glove 34 being placed thereon to bond the outer glove to the inner glove and the protective member. Once the outer glove 34 is placed over the inner glove 12 and the protective member 32, the outer glove cuff 50 is sewn to the inner glove cuff 30 so that the resulting glove 10 looks, fits and feels like a single glove.

In an additional embodiment, the outer glove 34 is placed over the inner glove 12 and the protective member 32 and the combined gloves are then coated in a polymer. The polymer soaks through the outer glove 34 and bonds the outer glove to the inner glove 12 and the protective member 32.

The outer glove 34 may have a first coating 52 on part or all of an outer surface to perform one or more functions. In an embodiment, the first coating 52 is nitrile for waterproofing. The outer glove 34 may have more than one coat of waterproofing material, such as for example, smooth nitrile. In addition to nitrile or as an alternative to nitrile, the first coating 52 may comprise a different waterproofing agent, such as polyvinyl chloride (PVC). In an embodiment, at least a portion of the glove, such as the front palm portion 46 of the outer glove 34, has a second coating 54 to impart certain desired characteristics such as, for example, improved grip. In an embodiment, the second coating 54 is sandy nitrile for improving grip. In additional embodiments the second coating 54 may be, for example, polyvinyl chloride (PVC), polyurethane (PU), latex, silicone and neoprene. Coatings may be placed on the outer glove prior to or after assembly of the overall glove 10.

In an embodiment, the inner glove is a knit glove of natural or synthetic fabric. In an embodiment, the outer glove is a knit glove of natural or synthetic fabric, natural or synthetic leather, fire resistant fabric or cut resistant fabric. In additional embodiments, the inner glove and the outer glove may be made from, for example: acrylic, fleece, wool, nylon, cotton, polyester, High Performance Polyethylene (HPPE), aramids (e.g. Kevlar), and blends of thereof.

Once assembled, the outer glove 34 conceals the inner glove 12 and the protective member 14. Concealing the protective member 32 makes the glove sleeker in look and performance. The protective member 32 will not snag on tools, machines and clothing, trap debris, or break or chip when exposed to abrasive contact. Also, when the outer glove 34 is coated for waterproofing, any water, oil, grease, or mud will not absorb into the material of the outer glove. Advantageously, the protective member 32 and the inner glove 12 will also be protected from water, oil, grease and mud and this allows for the use of more types of materials for the protective member 32 and the inner glove 12. Also advantageously, the outer glove 34 allows the impact resistant protection to last as long as the glove's useful life.
